Abstract:

Coffee has been one of the largest consumed food commodities around the world due to its specific flavor, taste
and physiological functions. The bioactive components in coffee with refreshing, anti-depression, antioxidant, antibacterial
and anticancer activities include caffeine, chlorogenic acid and melanoidins. Therefore, separation, determination and safety
evaluation of functional components in coffee have become a hot topic among researchers. This article reviews the research
progress in the separation, determination and safety evaluation of caffeine, chlorogenic acid and melanoidins in coffee. It can
serve as a forefront scientific reference for the study and application of functional components in coffee.

Key words: coffee, caffeine, chlorogenic acid, melanoidins, extraction, determination, safety evaluation
